Describe the bug
Running MC 1.15.2 with latest forge release. Holding a meteorite compass causes a server crash. Attempting to join the server after starting it again gives a buffer overflow error. (Deleting the item from the player inventory does not remove fix the issue)

To Reproduce
Hold a meteorite compass

Expected behavior
Item is held and points towards the closest skystone meteorite.

Additional context
Unable to grab error at the time of writing will update later.

Environment
Minecraft 1.15.2 using Forge 31.2.31
Other Mods are running in this environment (please notify me if the modlist is required)
Last Server Debug Log: https://pastebin.com/FA6pJzSZ
Server Crash Log: https://pastebin.com/dQhMrrkC

Given the crash log this might be more related to a (fluid) annihilation/formation plane.
I am looking into it.

edit:
Yes, this is unrelated to sky compasses. The packet handler for "transition effects" uses client-side only classes and it's internal methods were not annotated with "client-only" causing the server crash whenever that packet is even tangentially used.

Should be fixed in next alpha build.
